StandoutExceptional marine biodiversity

Cabeza de Mono offers a good Caribbean dive, typically calm and shallow, making it perfect for newer divers or those looking for a relaxed multi-level profile. You’ll find healthy hard corals and sponges here, often sheltering nurse sharks resting under ledges. Keep an eye out for green morays, they’re pretty common, and we’ve seen schools of snapper too.
